Hatsune Miku Live Party 2011 - Rave 18 Movie Theater - 11/10/11
Personal bias: I've seen Hatsune Miku in concert.
The crowd: Junior high and early high school kids, many with their parents.
Random notebook dump: I'm listening to kids scream during a concert film for a singer who isn't human. The line between fiction and reality may not exist much longer.
